So, in the first map, you went on to do some random jumping to places you're not supposed to go (I assume it's this one right here in the screenshot).

i fell between some flying boxes

On the second you listed, the door the revenant opens is supposed to close immediately as you go near it. You are NOT MEANT to go through it in that direction. I have no idea how you even managed to do that.

i didnt go in there from revenant side,every door was blocked by walls

I just finished playing through (finding the secrets made me feel blind when I found the switches, heh) and I had a blast. There was a nice mix of slaughtery maps and more unconventional maps that kept me going until the final boss fight, which I also enjoyed, having a nice variety of moves.

The only bug I came across was the zscript crash at the end of Point Motion (but I see you've addressed that for the next version), but other than that, everything else was golden.

Spoiler:

If I had managed to actually complete all the levels, including the secrets (because I couldn't finish Point Motion without the crash), does the ending change at all? Just curious.

Co-op compatibility with up to 8 players (not fully tested, so please report if anything screws up). Various maps will have special additions such as co-op teleporters for areas that "lock in" the player, or tweaked respawns.

Increased boss area size in SECRET01, should be easier to move around in now.

Replaced music in SPOOK05 again.

Made SPOOK09 shotgun faster (automatic, no reload).

Dive Suits in SPOOK09 now last two minutes, respawn in co-op, and are only active while underwater. In addition, a HUD indicator will appear showing how much air time they have left.

Fixed 3D floor crusher in SPOOK09 (not that this matters much since the room is empty now.

Added a small platform to the boss room of SPOOK12 so it's easier to shoot it.

Automap is now properly hidden in SECRET03.

Use ACS_ExecuteAlways on doors in Hub and SECRET03. This allows multiple players to go through doors without any problems. Note that if another player is blocking the destination you'll be put on wait until they move away, otherwise this would result in accidental telefrags.
